Plant peacock spikemoss in the ground if growing as a ground cover, spacing plants 2 to 3 feet apart. Choose a shady area with a rich soil, such as one comprised of up of 2 parts peat moss, 1 part loam. For container plants, use a hanging basket or tall container so tendrils can spill over the sides. Place your container plant somewhere it receives indirect light.
Mulch the soil to control the growth of weeds if growing peacock fern outside.
Water your plants regularly to maintain a moist soil. Do not overwater or the plant roots will rot.
Fertilize peacock fern using a water-soluble balanced fertilizer diluted at half strength. Combine the half the fertilizer recommended for your size plant with the regular amount of water and pour this mixture over the fern.
Clip back individual tendrils if they grow too long to maintain the size and shape of your plant.
